It's a multiplayer bug. The turrets work but the projectiles are invisible and the turret models are also invisible AFAIK. The only way to fix the projectiles is to use missile turrets or no turrets at all.

In random bases turrets just no spawning.Example: https://youtu.be/5BYO3Oga9uUI have bases with attached CargoPods. In MP base has only core without any attached item.
